Title: Position controller of movable body
Inventor: OBO HIDEFUMI
IPC: H01F7/16
Filed: 1992-12-01
Abstract: PURPOSE:To make it possible to hold a movable body such as a shutter blade at a specified position without continuing the conduction of an electromagnetic device. CONSTITUTION:Movable bodies 6, 7 are already moved to the second position side by means of an energizing device 3. When a coil 1d is allowed to conduct in a first direction, a movable iron core moves the movable bodies to the first position side. And, when the coil is driven to cutoff, a permanent magnet 1e attracts the movable iron core and holds the movable bodies at the first position side. When the coil conducts in a second direction, the movable iron core separates from the permanent magnet and the movable bodies are moved to the second position side due to the energization of the energizing device.

Filed: 1993-12-22
Abstract: PURPOSE:To extend a vibration propagation path, to improve an absorption effect and to enable miniaturization by chamfering the edge of a substrate where spurious mechanical vibration outputted from an interdigital electrode on a piezoelectric substrate is propagated to and reaches and applying an absorbent. CONSTITUTION:Both edges of the piezoelectric substrate 1 are chamfered and chamfered parts 11 are formed. Thus, the spurious mechanical vibration advances along the chamfered parts 11 to the rear side of the piezoelectric substrate 1 and is reflected at a lower edge. Thus, the propagation distance of the spurious mechanical vibration is extended to approximately 1.5-fold and by applying a sound absorbent 12 there, an attenuation effect can be improved to be 1.5-fold with a size approximately the same as in a conventional case. Further, since the surface of the chamfered parts 11 is not smooth, the spurious mechanical vibration is scattered and attenuated further.
